To all the IT people that say that they cannot have a filter because A. they need unfiltered access. B. they can always find a way around.
Please note that you can always unblock a site that is blocked. and the idea of a filter (as I heard from a Rav) is not to have fool proof filterezation, rather that you shouldnt have open access all the time, the fact that you know of a way around the filter, doesnt mean that you should not have one in place. its much better to have it i place, since if you do want to go to a site that is unappropiate, you should at least have to work your way around, it shouldnt be a click a away
